Apparatus and method for interfacing with a cell-phone network

摘要

A smart card for use with a mobile communication device adapted to communicate over a cell-phone network, the smart card comprising: at least one communication port for communicating with a transceiver via a communication channel that is not a cell-phone channel; and a processor configured to receive from the transceiver an IMSI from a SIM having an authentication key, and an authentication response generated by the SIM responsive to the SIM's authentication key and a challenge by a cell-phone network, and to transmit the received IMSI and authentication response to the mobile communication device for transmission to the cell-phone network via a cell-phone communication channel provided by the cell-phone network.

1. A smart card for use with a mobile communication device adapted to communicate over a cell-phone network, the smart card comprising:
at least one communication port for communicating with a transceiver via a non cell-phone communication channel; and a processor configured to:
initiate a request for, and receive from the transceiver via the non cell-phone communication channel an IMSI from a SIM having an authentication key and located in a SIM server comprising a plurality of SIMs;provide the mobile communication device with the IMSI;request and receive from the transceiver via the non cell-phone communication channel an authentication response generated by the SIM using the SIM's authentication key in response to a challenge that the cell-phone network transmits to the mobile communication device in response to the cell-phone network receiving the IMSI from the mobile communication device; andtransmit the authentication response to the mobile communication device for transmission to the cell-phone network via a cell-phone communication channel provided by the cell-phone network, wherein the smart card has a physical format of a SIM card.
